Brain imaging is based on measuring not neural activity but rather, brain hemodynamics – local changes in blood volume, blood flow and oxygenation. These hemodynamic signals are understood to reliably report local neural activity. In particular, it is typically assumed that the hemodynamics follow uniformly from local neural responses, with increases in neural activity...
